HOSE OR TUBING.

SPECIFICATION forming part of Letters Patent No. 398,480, dated February 26, 1889.

Application tiled October 20, 1888. Serial No. 288,629. (No model.)

To all whom it may con/cern.:

Be it known that l, THOMAS MIDGLEY, a citizen of the United States, residing at Beaver Falls, in theeounttT of Beaver and State of 5 Pennsylvania, have invented certain new and useful Improvements in Hose or Tubing; and l do hereby declare the following to be a full, clear, and exact description' of the invention, such as will enable others skilled in the art to which it appertains to malte and use the Sftllle.

bear upon the hose, while it. is rendered much i lighter and more flexible.

The invention will be hereinafter 1 scribed, and particularly pointed out in [he claims,

In the accompanying drawings, which form part of this speeitication, liigure l represents a plan view of a section of a sheet of wire. Fig. 2 is a side elevation ot' a tube formed from a sheet of wire, and Fig. 3 is a similar and an end view of a section of hose partly eo'vered with rubber.

Reference beingI had io the drawings and the letters marked thereon, A indicates a sheet oi? wire made from sections rt of coiled wire, which are intertwined. by serewing one into another until a sheetbt' any desiredV length and width has been formed. After the sheet has been thus formed it is wound sliiiallyv around a mandrel and the adjacent edges scoured together by screwing a separate section, b, of coiled Wire into the helices on the edges of the sheet and a I tube, B, formed, in which the helices c run diagonally around the tube.

The tube ,ll is thenpassed through a furnace and heated to about a eherryred heat and the helices e stretched and flattened into links d, which are seated in each other by subjecting the tube to longitudinal tension While passing through the furnace. In stretching the tube Bits length is increased about two and a half times and its diameterreduced about the same proportion, as shown by the tube C in Fig.

The tube B may be stretched b v any suitu able meansmsueh as grasping the front end ofthe tube as it comes out of the furnace with a clamp or a pair of suitably-cou` strueted tongs and atta-ching them to a tension device, by which sufficient force can be exerted upon the tube to stretch all the heliees to their full extent. ln stretching the helices of the tube B they retain their diago nal course around the tube, and the tube C is consequently composed of links which run at an angle to the length and cross-section of the tube, thus providing the greatest degree of resistance possible to be obtained against longitudinal and lateral strains brought to bear upon the hose by high pressure of Huids. The tube .O then tempered and afterward lined with canvas, e, and rubber, f, and covered with rubber, g, or its equivalent, and the whole subjected to heat to vulcaniZe the rubber, ol it may be lined only for some classes of hose.

Hose thus eonstrneted is of the saine weight as that ordinarilyv made troni rubber and canvas, and will collapse when being wound upon a reel, while it is capable oi resisting the weight ol ordina'n-yv road-vehicles when filled without detriment to the hose.

rlhe hose may be made ot' anyv desired diameter, and in lengths to suit any use to which it may be desired to use it.

The tube l is elainied in in v applh-zition Serial No. 2SS,G27.

Having thus fully described my invcintitni, what l claim isl. Ilose or tubing composed ol a bodyr con f sisting of intertwined helices stretched to their full extent and running diagonally around the tube, and a lining ol' Huid-repellent material, Substantially as described.

2. Hose or tubing composed of a body cou- Sistng ol 'intertwined elongated llelloes running at an angle to the length, and also at au angle to a Cross-section of the tube, a lining', and a covering of fluid-repellent material, substantially as described.

In testimony whereof I affix my si gnature in presence of two Witnesses.

THOMAS MID GLEY.
